RADICAL SCAVENGING ACTIVITY OF SILYMARIN ENCAPSULATED IN LIPOSOMAL VESICLES: IMPACT OF UV IRRADIATION AND LYOPHILIZATION
Silymarin exhibits plenty of bioactivities that can promote human health and well-being. Nevertheless, silymarin is poorly soluble and possesses lower bioavailability, thus, its application is quite limited. Liposomes can increase the stability of encapsulated sensitive compounds and the bioavailability of poorly hydrosoluble components. Concerning...

COVALENT IMMOBILIZATION OF HORSERADISH PEROXIDASE ON BIO-LINKED MAGNETITE NANOPARTICLES
Enzymes, such as peroxidases, are “green” catalysts used in various environmental processes. Enzymes can be used in free form or immobilized on a solid support such as metal oxides, carbon and composite materials. The appropriate choice of carrier can significantly improve the properties of the enzyme, increase its stability and enable ...

NONPARAMETRIC STATISTICAL TESTS APPLIED TO WATER QUALITY INDICATORS
To minimize the risk of infections, it is essential to routinely test for bacteria and harmful contaminants, particularly in areas where water is utilized for drinking or recreational activities. To demonstrate the presence of microbiological indicators (Escherichia coli and intestinal enterococci), water sampling and analysis were conducted at Jar...

MATHEMATICAL MODELING OF NICKEL REMOVAL BY COAGULATION AND FLOCCULATION PROCESS
In this study, the effects of coagulant and flocculant concentrations, as well as their interaction on the efficiency of Ni removal through the coagulation and flocculation process of real wastewater from the metal industry were examined. A 3² factorial design was used for the design of the experiment, with two independent variables: coagulant...

ION EXCHANGE OF Na+ IONS WITH H+ IONS ON ZSM-5 ZEOLITE USING ACETIC ACID
Based on previous research into the acid-base and ion-exchange properties of ZSM-5 zeolite, there is a need to explore the possibility of ion exchange on high-silica ZSM-5 zeolite with commercially available chemicals, while simultaneously monitoring changes in the structural and morphological characteristics of the zeolite, as well as the stabilit...

EXAMINATION OF HYDROXYAPATITE APPLICATION AS A POTENTIAL QUERCETIN - CARRYING MATERIAL
The objective of this work was to investigate a naturally occurring mineral form of calcium apatite, known as hydroxyapatite (Hap), as a potential drug delivery material. Drug delivery materials are utilized to effectively administer drugs to the body, ensuring controlled release, targeted delivery, and enhanced bioavailability. Hydroxyapatite was ...

ASSESMENT OF THE CURRENT WATER QUALITY STATUS OF THE DRINA RIVER AT SELECTED SITES
To assess the current water quality of the Drina River, water samples were collected from the river and its tributaries at selected locations. A total of 17 samples were taken from various points along the Drina River, including Foča, Višegrad, Bratunac, Zvornik, and Bijeljina, over a period from June 2023 to September 2024. The analysis foc...

PRELIMINARY ASSESMENT OF THE USE OF RED MUD SLAG FOR PHOSPHATE SORPTION FROM AQUEOUS SOLUTIONS
This paper shows the preliminary results of the investigation of the possibility of the use of red mud slag (RMS) for phosphate sorption from aqueous solution. The red mud slag was obtained from red mud treatment, specifically carbothermal reduction at high temperatures. This process resulted in forming a metallic phase (iron) and slag enriched wit...
